. Theobject of t'he invention isqto furnisha means of. confining-and supportinga tuft such a cleaning. device, and of exposing successive 1 portions. of the tuft )as the end is wornjawayl'i When desired the operative end of the tuft maybe held in a form ;of flat or .ova lcross section, and to confine said end;.;a metal jcasingis' ap plied thereto to confine and supporttheexposed portion of the tuft. In this invention the greater part of theth'ft is confined and supported by a wrapping of paper or equivalent material to form a holder-for the body of the tuft. Sucha. .WrappingxisSreadily wound so as to present a yielding conical end; and

ing, and when such a casing is applied to such a wrapper over the yielding conical end, it operates to mold or force the Wrapper and fibrous core or tuft to the shape of the nozzle, and the mere application of such a nozzle to the wrapper and tuft thus serves to hold the normally round tuft in any desired cross section when in use.

The device which attains the object of the invention consists primarily of a tuft of fibers such as metal or spun glass adapted to effect cleaning or erasing, and a wrapper covering the body of the tuft to form a holder for the same and having sections of detachable character which may be successively removed to expose a new portion of the tuft-body as the end is worn away.

and portions of the holder successively removed.

.To facilitate the windingof the wrapper if. usedto form the holder thebody of the tuft is preferably made of cylindrical forn'wand when the operative end of tlletuft requires a sflat oroval shape; a metal casing is applied :to thewra'pper and provided with a nozzle tapering to its smaller end and having an-oval opening. The lengthof the exposed portion of the t'uftmay be several times the length of the ortion necessary to" project thus as the tuft is worn away the nozzle may be moved back ward to expose a new; working portion. Such an excess length of unwrapped tuft offers another advantage,- namely :-when the working portion of the tuft at the end of the nozzle becomes clogged or' filledjw'ith smallv particles of carbon or products of erasure. the casing may be readily removed and the tuft fibers spread apart, and the productsbf erasure removed by rubbing them over a straight edge.

tuft for a considerable portion of its length.

Theoth er end of pfbvided with a fiber the wrapped tuft be brush away the products of erasure.

The invention will be understood by reference to the annexed drawing in which Figure 1 is a side view of the wrapped tuft; Fig. 2 a view of the wrapped tuft with a metal casing on one'end; Fig. 3 is an end view of Fig. 2; Fig. 4 is a longitudinal section of Fig. 2; Fig. 5 is a side view of the cleaning device with a flattened nozzle at one end and a brush at the other end; Fig.

7 6 is a View at the right hand end of Fig. 5

Fig. 7 is a longitudinal section of Fig. 5; Fig. 8 a view of the brush detached.

Figs. 2 and 4:, show a fibrous tuft a having a wrapping of paper or analogous fabric, such wrapping having detachable sections formed by the configuration of the fabric, which thus forms a covering or holder 6 of cylindrical form, having one end a tapered, from which tapered end the workingportion of the tuft projects a suitable distance. Such wrapped tuft may be of suitable size for use in cleaning china, metal etc. but where the tuft is made relatively small as for use in an eraser, the cas for sweeping WitllOUt the extended support for ing (Z is of tubular shape adapted to fit snugly upon the wrapper b. One form of said casing is shown in Figs. 2 and l being tapered at one end to form a nozzle f so that the inner wall of the nozzle contacts I for supporting the working this construction a sufficient part of the tuft may be exposed as required for repeated use; the nozzle being slipped backwardly upon the wrapper as the tuft is used up; Which avoids the repeated removal of the nozzle to unwrap the tuft. For many uses this construction affords all the support that is necessary for the tuft.

By the use of paper or equivalent material, the Wrapper in which the tuft is contained is made yielding, and when the nozzle is oval or of other form in cross section, will readily adjust itself to the form of the nozzle and thus adapt the tuft to any variation in form. a

When the Wear upon the end of the tuft makes it necessary to provide a new working surface, a section 9 of the covering (see Fig. 1) is removed and a new portion of the tuft is thus exposed. Where a metal casing is used, the said casing is removed and replaced after the section of the wrapper has been detached. In the manufacture of the eraser the working length of the tuft copies of this patent may be obtained for five cents each, by addressing the Washington, D. G.

ated to form an extended tubuto be exposed may be varied by varying the width of the detachable sections, wrapped upon thetuft. a I I a The end of the holder opposite to that fromwhich the tuft projects may be equipped with a removable brush it com- ,posed ofbristles secured in a suitable shank it, such shank being adapted to fit an aperture i in the holder. This brush may be permanently fastened into the holder. by a cement or may "be removable therefrom, and as the-eraser may wear outbeforethe brush, the brush may be preserved and insertedin ajnew eraser.

Now having described myimproveinen'ts 9 of the core as the latterbecomes worn through use, I and a tapering sleeve removably securedupon the holder and adapted to confine and support the strands of the core and to follow up the same as it is worcp and the holder progressively short ene;

In testimony whereof I have hereunto set my hand in thepresence of two subscribing witnesses; I v I a p nmrswitrna GREENBOWE.
